IMPROVEMENT IN THE LU-BRICATING OF SPINDLES.

Specieation forming part of Letters Patent No. 40.678, dated November24, 1863.

.To all whom it may concern:

Be it known that I, JAMES EATON, of Boston, in the county of Suffolk andState of Massachusetts, have invented an Improve- Inent in Lubricators;and I do hereby declare that thefollowin gis afull and exact descriptionthereof', reference being had to the accompanying drawings,` making apart of this specication, and to the letters and figures marked f.thereon.

Figure I is a plan of the mechanism; Fig. II, an elevation of the fixedpart of the same; Fig. III, an elevation ofthe movable lubricator; Fig.IV, a plan of the same; Fig. V, a section on the line A B, Fig. I; Fig.VI, an enlarged section of a spindle-bearing.

The object of my improvement 1s to afford a constant supply ot' oil tospindles while they are in motion, by which they are always kept in goodrunning order, instead ot' being at one time nooded with oil and atanother nearly dry. At least one-halt' the oil now required firlubricating spindles is saved by my improvement.

I am aware that various kinds of fibrous substances have been used forconveying oil to bearings, as inrailway-axles, te, and my improvementrelates merely to the manner of applying the oil, fat, tallow, or othersubstance used for this purpose. The mechanism for effecting this isshown in the drawings. The rail C, that attords a bearing for thespindles, extends across the mule or spinning.

frame, and the bearings, instead ot' being circular, as usual, aresemicircular, as at D, at the point of contact with the spindle, thewhole form of the bearing being shown enlarged in Fig. VI. This form isused for the purpose ot' exposing the spindle. 'as at S, Fig. II, insuch a position that the oil may be readily applied.

The lubrcator consists of a case, E, Figs. I, l

III, IV, V, which has atop, bottom, and front side, and within it apiece of felt, sponge, or other suitable fibrous substance, G, isplaced,

the breadth of the case and inclosed felt being equal to the height orlength of the bearing. Clamp-springs F F are attached to the rail andproject from it a distance equal to the breadth of the case E. Thespindles S S are held in close contact with the bearings D by thedriving-bands, and need no support upon the opposite side. is slippedbetween the clamps, and the open or exposed side of the spindles restsin contact with the felt G, which is saturated with oil. The top ot' thecase projects over the rail, as seen in Fig. V, and protects the bearingfrom dust and dirt. The clamp-springs F are pressed forward when closercontact of the felt with the spindle is required. The movable case canbe readily lifted out, and the spindles can be adjusted with greatfacility by the use of my improvement.

, Although [consider the bearing ot' the. spindle upon one side (whilethe other is exposed to the lubricator) as sufficient to insure itssteady action, an additional bearing may be formed by making the edgesof the semicircular cavities at H in the4 top ot the case of suitablethickness for this purpose.

When bearin gs are made in the case, as

above named, it will be necessary to give it av iirm support and a iixedposition with reference to its distance from the spindle. This may beeffected by'form-ing a rabbet in the rail, as at- R, Figs. II and V, andfitting the top otl the case accurately to it.

What I claim, and desire to secure by Letters Pat-ent, is-

The movable case, containing the lubricating substance, and having oneof its sides open, in combination with the sernieircular main bearing D,which allows a spindle tov come in contact with the lubricating subistance, substantially as herein described.
